Application filed June 11, 1924. Serial No. 719,244.

This invention relates to anchor tie-rods and with regard to certain more specific fea tures to tie-rods for anchoring door and window jambs or the like to walls of. concrete, masonry or other like material.

Among the several objects of the invention may be noted the provision of a simple and cheaply made device for anchoring jambs to walls, a device having a universal application to all sizes of jambs and all ordinary types of walls including concrete, brick, stone and tile construction, and the provision of an anchor having a large gripping area, an anchor that will not shrink and one that is visible during the period of construction of a wall to which it is applied. Other ob-- jects will be in part obvious and in part pointed out hereinafter.

The invention accordingly comprises the features of construction, combination of ele ments, and arrangements of parts, which are exemplified in the constructions hereinafter described and thescope of the application of which will be indicated in the following claims. a

In the accompanying drawing, in which is shown one of various possible embodiments of the invention,

Fig. 1 is a horizontal section of a brick wall taken along the line 1-1 of Fig. 2, and shows the anchor tie-rods in position. between the wall and jamb.

Fig. 2 is a verticalsection of a wall taken along the line 22 ofFig. 1.

Fig. 3 is a top plan view of one of the anchor tie-rods.

Similar reference characters indicate corresponding parts throughout the several views of the drawings. 7

Referring now more specifically to Fig. 3 there isillustrated an anchor tie-rod 1 constructed of light iron wire, number 8 gage being suitable for thickness. The use of metal makes an unshrinkable construction. This tie-rod 1 is pressed to a chisel edge 3 at one end. said chisel edge 3 being vertically disposed for easy driving into such vertically grained wood as is encountered in jamb construction. p

A short distance away from the chisel edge 3 the wire is bent to a right angle 5 and at about twice the aforesaid distance from the right angle 5 the wire is bent again in the same direction but at an obtuse angle 7 From the obtuse angle 7 at approximately the distance equal to the distance between with this improved the chisel edge 3 and the right angle 5 the wire is bent in a reverse direction from the aforesaid bends and forms the reverse obtuse angle 9. The wire now follows a direction approximately 45 from its direction between the chisel edge 3 and the right angle straight portion there is formed the reverse quarter turn 11, said quarter turn 6 being cut to a point 13 in the process of manufacture.

The chisel edge 3 and the stem 15 joining said edge to the right angle bend 5 form the wedging member which is driven into the jamb 17 (Figs. 1 and 2) thereby providing an easy method of applying a jamb anchor.

The obtuse angle bend 7 and the obtuse reverse bend 9 serve to bring most of the remaining portions of the anchor (the leg 19 and quarter turn 11) in between the edges of the jamb, to take care of cases where the wall is no wider than the jamb itself.

The reverse obtuse-angle 9 and the quarter turn 11 serve to prevent the wire anchor from being pulled out of its imbedding material in a direction lengthwise of the leg 19. The gripping action of the tortuous wire (9, 19, 11) is of great advantage, especially when shrinkage of a jamb takes place. The wire 23 of this anchor is put into tension when jamb shrinkage takes place, because the leg 19 is anchored firmly as described, and the shrinkage movement of the jamb is away-from the wall. This puts the portion 23 in tension. Thus a structure equipped anchor becomes more rigid as shrinking goes on, whereas heretofore, the reverse of this last statement was true. Shrinkage loosened. the anchoring means themselves in previous anchor constructions.

The device is put to use in the following manner: 4

Assuming that a wall of brick isv being built the 'iamb 17 is put in place and the courses 25, 27, 29 and 31 of brick are brought against it, layers of mortar being applied between said bricks.

The jamb 17 should be anchored to the wall at intervals. The distance between jambs may vary. One anchoring is provided for by driving horizontally into each side of the jamb an anchor tie-rod, one

slightly .above the other so that their legs 19 Will cross at a point 21. Each of the Wires lies in a horizontal plane. They are driven slightly above the last course of brick just before mortaring the exposed surface of said bricks. After the anchor tie-rods have been driven home the surface of the last course of brick is mortared and the next course applied, thereby binding the anchor tie-rods permanently in place. The convenience or this application is apparent.

The tie-rods can be applied to any wall ivhere an originally plastic material is used in the construction of: the same. Neither are they limited in application by the type of door or window jamb used, varying widths of ainb merely varying the point of crossing 21 of the anchor pairs. The use of the anchors in pairs keeps the jamb from pulling away on either side of the Wall.

It should be noted that the straight portion23 of the tie-rod betivee'n the right angle bend 5 and the obtuse anglebend? serves "the useful purpose of presenting to the eye the exact location of every anchor tie-rod The construetion niay thus be easily checked for bracing after the completion of Work upon it.

In View of the above, it will be seen that the several objects of the invention are aehie'vel and other advantageous results attained.

As many changes could be inade'in carrying out the above constructions; Without departing from the scope of the invent-ion, it is intended that all matter contained in the above description or shown in the accompanying drmvings shall be interpreted as illustrative and not in a limiting sense.

I claim: v y

1. An adjustable anchor -for Wall jambs comprising a pair of separate \vire elements, pointed portions "formed on said elements for application of the elements to jambs and the like, portions angularl'y arranged with respect to said pointed portions for indi'cating the position or the elements during a course of construction, and anchoring portions angular-1y arranged with respect to all of said named portions whereby the anchoring portions are adapted to e'zttend into the body of a Wall in a predetermined position When the jamb is placed next to said Wall.

2. An adjustable anchor for wall jambs comprising tWO separate Wire elements; a U-shaped portion formed in each element having one leg pointed and adapted to be driven into the side of a jamb, and a tor tuously shaped anchor portion formed integrally With the other leg of said U-shaped portion of each element; said anchor portions being curved inwardly to lie Within the body of a Wall substantially Within the projected planes'of the sides of a jamb into which the said pointed legs are'driven.

3. An adjustable anchor for Wall jambs comprising a pair of separate Wire elements, pointed portions formed on said elements for application of the elements to jambs and the like, portions angularly arranged with respect to said pointed portions for indicating the position of the elements during a course oi construction, and anchoring portions extending angularly from said portions being adapted to extend substantially within the limits of the projected planes of the sides of the jamb to which the elements are applied.

a. An adjustable anchor for Wall jambs comprising a pair of sepa ate ivire elements, pointed portions formed on said elements for application of the elements to janibs and the like, portions angularly arranged with respect to said pointed portions for indicating the position of the elements during a course of construction, and anchoring portions so arranged With respect to said an gularly arranged portions that said anchoring portions cross one another Within the lateral projection of the edges of jambs of various Widths to which the elements may be applied.

5. In an anchorage for Wall jambs, the combination of a pair of separate Wire elements each comprisingv a flattened end-portion for driving and fastening into jamlos, means for limiting the depth of driveand keeping the element partially visible, said means comprising a right-angle bend, a straight portion limited by a hooked end for fastening said elementinto plastic lnaterial of a Wall, abend between the straight portion and the right-angle bend for bringing the Wall end fastening Within the limits of the projection of a jamb, and a bend be tween the straight portion and the last named bend to provide a tortuous efiect and consequently better gripping qualities.

In testimony whereof, I have signed my name to this specification this 6th day of June, 1924. V H
